Thanks! As usual, one of those times when you drive home from a hike with your eyes peeled and things happen right in front of you. Starting to get in the habit of always throwing the telezoom on for the drive home, just in case.
I agree that the birds need more prominance. I'm not sure how to without messing up the already strained pixels there. It's not the greatest lens, althought without it I wouldn't have got the photo at all.
Lux, I echo what others have said. That's a fine shot.
